[Q] Issue with Google Edition ROM, something about android.core has stopped working.

So I just installed the Google Edition rom on my Sprint GS4, and the actual install process went smooth, but as soon as the boot process is complete, the phone slows to a crawl and something to the like of "the process com.android.core has stopped responding" and then I get a force close button that I can not push. I'm wondering if anyone else has had this issue on the Sprint variant of the GS4 and if anyone has had a workaround with the issue. I have flashed back to stock rom currently, but I can reinstall the rom (like I'm going to do anyways later tonight). I used the rom located here.

Make sure your wiping system in refovery before flashing. Need to wipe cache, system, and data, and preload at times but doesnt hurt to wipe it anyways. Wipe everyrhing 2x then flash the rom.

Thanks! That worked! Good learning experience too. Kind of my first time flashing a rom to any phone, (I had a motorola photon before this phone, and i was satisfied with stock rooted on that phone, not so much with the gs4).

anyone know how to get rid of the voicemail notification on GE

All ROMs I flash on my device have become unstable

I've had my S4 for a little over a week now. I've been flashing different ROMS to find which one I like but all of them except for CleanROM are very, very unstable on my phone. I've tried CM, SlimBean, Graviton, and PACMan. Some are TW, some are AOSP but I get the same results for each. Device becomes unresponsive, I get FCs, random reboots. Its crazy because I had no issues at all on my Note 2. I wipe and factory reset every time, its becoming very tedious to restore each time. I do not restore system apps, I follow all instructions and still get these results. I'm wondering if I have a faulty device? Maybe a sensor or something is not liking certain things on certain apps? I've noticed that after I installed Graviton and went back to CleanROM, Titanium has stopped working and I get the Samsung lockscreen instead of the SGS4 one. I may just go back to MDL stock in Odin, re-root and see what happens...I'm currently wiping everything and fixing permissions

Sorry to hear, sometimes starting over cures 90% of all issues, and the os gets better each time.. If it were me, I would quit wasting time and odin.
Thanks, and good luck.

Don't forget to immediately freeze the ATT update apps... Or you will get the MF3 OTA... which, for now, is NOT-ROOTABLE & Custom Recoveries NOT-Installable.

I always factory reset,wipe both cache and format system.even when I use a back up.

Well I ODIN'ed and went back to CleanROM. So simple. I'm dying to try one of the VZW AOSP themed TW ROMs though. Decisions, decisions. Oh man....when I first got the phone it was on MF3. I spent 3 days on craigslist and found someone to trade me their non-updated phone. Still new to this Android business. So far I love it. Don't see why I spent so many years hating. Thank you all for the help.

[Q] Stock Nexus became extremely slow after kitkat

I am all stock on my nexus 7 wifi, updated to kitkat using OTA. But the tablet has become laggy and unresponsive. SD card read write has slowed down, There used to be more apps loaded in memory while on 4.3 but only a few are there now. I wanted to know what are my options other than rooting and installing custom rom??
Sent from my Nexus 7 2012 wifi

I had the exact opposite from my N7 wifi. It had become barely usable before the update. Apps taking forever to load, apps hanging or crashing, real laggy. It's stock, just rooted.
The OTA update made a huge difference for the better. That's what I've been hearing from others too.
It can be a PITA but I would make note of the apps you want and get your saved stuff off (pics and docs etc) and wipe it with the factory kitkat image from Google.
You shouldn't be experiencing what you are.

Reflash or just factory reset??
Sent from my Nexus 7

I have the same problem. KitKat has has made my nexus 7 so slow. When I looked on the net some people say a factory reset sorted this out but some say there was no change. Think its so bad Google put this update out without testing it properly. As there seems to be lots and lots of people with this problem.

like skrusrnmz said, i m beginning to think incremental updates break something about apps and system slows down. flashing fresh stock from scratch might solve it...lets see.

+1 Before the KitKat 4.4 OTA, the N7 2012 WiFi was already running on a series of patches and updated Apps via Play Store, getting sluggish & running low on space. For anyone that's on XDA, you know how easy it is to unlock the bootloader & get root after flashing custom recovery via ADB (try not to use toolkits - as a last resort or for the lazy ones, LOL)
If you have custom recovery already (and, I recommend & recommend TWRP over my long favorite - CWM) just reset, wipe cache & dalvik and use one of the flashable zip - after doing the proper TB backup & TWRP backup to a secured storage media. Push recovery again if necessary, along with Busy Box & SU v1.75) - reboot & setup the basics - then restore TB (w/o data to avoid errors) and let it stabilize with any newer update, finalize tuned settings. End result - a smooth rooted stock rom & kernel on 4.4 which is what I'm running for the last 2 weeks ... until developers can do their magics on both odexed & deodexed roms with their tweaks.
If you aren't happy with the results, you can always restore your saved images from custom recovery & go back to 4.3.1 or what now - but, IMO, you will appreciate & learn to like KitKat.

My 2012 Nexus 7 was slow before the KitKat update. Afterwards it was dog slow. So I did a factory reset. It's now back to being buttery smooth.

Yeah I think it's an issue with updating and not wiping. I just flashed the image myself and yeah it's smoother

i think it may be you have too many file on your device. try to delete some file. it should go faster

I had the same problem when upgraded from 4.2.2 to 4.3 and never resolved with stock firmwares.
Try a factory reset, but it's not guaranteed that it will work.

I have factory reset my device before installing fresh stock, its better than before. will test a few days, otherwise fresh installation.

[Q] Unbelievable lag on lollipop

I flashed the android 5.0 image from google website using NRT and then rooted the device. I have TWRP 2.8.1.0.
The problem is that my nexus 7 2012 12GB is giving me unbelievable lag. I have cleared cache and all but it is of no help.
I have no idea about F2FS but I read that changing to F2FS might help. So can any of you tell me what to do.

I had that problem when I first flashed the factory 5.0 Image, without wiping data. It was horrid. The situation didn't improve after wiping data.
Later I flashed the ROM in my sig, and it is working very good. Occasional lag, but nothing worse than kit-kat. Overall the performance is much better than kit-kat.
I made sure to wipe, format, and repair data, cache, and system. In fact, that ROM wouldn't even boot until I did.
I wiped, formatted, and repaired, then loaded the ROM and GAPPS manually via ADB and flashed both normally using the TWRP interface.
Bootloader: 4.23
TWRP: 2810

Factory reset does wonders. Lollipop works great after

I was having the same issue, then uninstalled Facebook and it has been fine since.

I had lag issue with google launcher. I am using launch came with Rom and nexus is much better. I am using f2fs Rom w/o google launcher. It's very usable.

I turned on Develop Options then scrolled to the bottom and checked off "Kill all activities when you leave them" and I really don't have the lag anymore.

Thank you for this tip. I did this and now its like having a whole different tablet. It is usable again. The only thing is in my developer options it is called "Don't Keep Activities."

I was writing the post from memory but your correct on the name. Glad it helped.

Also, scale all the animation speeds down to 0.5x in Developer Options and you'll love the snappiness It works great on my Nexus 7.

wiped cache, 'Don't Keep Activities' and whatever i could find still laggy as sh*t. Will wait for 5.0.1 OTA if that doesn't work back to 4.4.4. Any other suggestions without resetting/wiping ?

Try to run fstrim on /cache and /data

try this fix
I was able to fix my nexus 7 2012 lagging problem after the lollipop update and now it is as fast as before. I posted a video on how I did it and there is no downgrade or rooting required. Here is the link youtube.com/watch?v=OH2iYdr91DE

u captured and uploaded a whole video just to tell us that the lag was fixed after turning location service off?!

I just received my nexus 7 2012, bought it from someone and it had 5.0.2 already installed on it.
This thing is sooo slow that i was wondering if i made a bad buy by getting this model.
Everything is super laggy, for example,.. 9gag or facebook, when it finally loads i cant scroll through it, its so slow it crashes the application before scrolling down.
I tried the wipe cache, enabled "dont keep activities" and set all animations to .5 in dev mode. i tried disabling location.
It all made it a bit more usable,.. but i read people having a smooth and fast device... which i dont have still.
what else could i try? as far as i know its not rooted and has the stock rom.
I really want to like this device but its not happening so far.
Any help is really appreciated

Most of the custom roms fix this issue. very fast now!

I am waiting for 5.0.3 and hoping it helps!

I am not going to hold my breath. After I did a full wipe & installed 5.02 that did seem to help.

I had really bad lag after flashing 5.0.2. I discovered (while trying to install Busybox) that the system partition was full. I deleted a few system apps (stuff I could get from Google Play if I ever needed it down the road), freed up a few megs, and things got instantly better.

Lost 1/2 my storage space
After factory resetting & flashing LRX22G on my 16Gb nakasi/grouper Nexus 7, it has turned into an 8Gb device... I've just spent the past 7 hours setting it all up again, so I am less than keen on factory resetting it all yet again to try & get it working as well as it did under Kitkat before I was stupid enough to upgrade to Lollipop. On the plus side, the horrible lag has finally gone (I think that it is the factory resets & cache wipes that fixes it, but I could be wrong). Now all I need to do is to find out how to convince it that it is a 16Gb version without having to factory reset it. Does anyone have any good advice on that please?

No, I take it all back! The horrible lag & frequent crashes are still here on 5.0.2 & exactly the same as they were on 5.0, & after an afternoon trying to use my tablet I am having no luck. Now my problem is that because I have lost half of my storage space, I don't have enough space to copy back my nandroid backup of my lovely, fast, & fully functional Kitkat installation.

Lollipop vs. KitKat Boot times - observation of twice longer booting LP vs. KK

Hi, have observed that my Z3 (D6603) boots almost twice as long after I moved from KitKat to Lollipop.
Previously I used LB rooted 23.0.1.A.5.77 (rooted .93 giefroot + DualRecovery + reflashed to PRF pre-rooted .77), deodexed and zipaligned, some slight debloated (Lifelog, SocialLive etc.) and with many apps removed from autostart.
Recently I flashed pre-rooted D6603_23.1.A.0.690 (Nordic), de-bloated (heavily, left just Camera, Album, Themes and system stuff), also removed almost everything from autostart.
However, my boot times on Lollipop are now 37sec. (56sec. before de-bloat) versus 22 sec. on KitKat.
I would like to know if you have similar experience and what can be possible cause. I understand the way ART works results in longer installation and possible first-after-install reboot, but above observed times are bit of disappointing.

Even though there is a difference, why does this thing bother you? I haven't rebooted my Z3 for around 1000h with the KitKat. This means that the software is stable and bug free. Why would you reboot it and taking care of rebooting times?

Me personally find lp boots much faster than kk, I haven't messed around with autostart apps and have not heavily debloated it. Have you timed the boot without disabling stuff and just as stock?

Yes. Fresh after install and initial configuration reboots stable at 56sec

You may be right but longer booting times may be indication of something went wrong.. So happy that you are not bothered but I am from principle.

My phone has a tendency to (random) stop enabling mobile data if I've been switching between wifi and mobile throughout the day. The only fix is to reboot the phone which means if I had to urgently looking something up I'd have to wait till the phone has restarted before mobile data works again. Hence, reboot time can be important but not a deal breaker.

Mine does the same on KitKat

Mine bootlooped if plugged into charger while turning on with lp, it was very odd.
But normal boots were noticeably longer than kk.

nevermind, my error, disregard post

My 6653 running 6603 FW and encrypted took 3-4 x as long to boot into LP
So I reimaged and wiped then did a reset from the phone and now it's okay. not slower not faster than before.
